Represent Rio Tinto, the world’s second largest mining company, in an SEC suit alleging violations of Section 10(b), 17(a), internal controls requirements and books and records requirements, concerning the timing of a more than $3 billion impairment taken in connection with a mining project in Mozambique.

Represented Vale S.A. in massive class actions relating to the collapse of the Fundao dam in Brazil. Defeated class certification in one class action, effectively ending it, and obtained dismissal of a second that was affirmed by the Second Circuit.
